Longest Common Subsequence 给出两个字符串,找到最长公共子序列(LCS),返回LCS的长度。 说明 最长公共子序列的定义: • 最长公共子序列问题是在一组序列(通常2个)中找到最长公共子序列(注意:不同于子串,LCS不需要是连续的子串)。该问题是典型的计算机科学问题,是文件差异比较程序的基础,在生物信息学中也有所应用。

The bottom-up dynamic programming approach discussed in this blog post provides an efficient solution to LeetCode 1035 – Uncrossed Lines problem. By leveraging the concept of the longest common subsequence, we can determine the maximum number of uncrossed line...
Leetcode-Longest Common Substring(最长公共子字符串) 2018-12-02 15:07 −# Longest Common Substring 最长公共子字符串 >动态规划问题 动态规划问题的两个特点: 1.最优子结构 2.重叠子问题 因为有重叠子问题,当前计算的过程中可能有的问题在之前的计算已经计算过了,现在又要计算一遍,导致大量重复的计算。
